Past Tense (-di) in Turkish

In Brief

Use the Turkish -di past for a completed event that you experienced, witnessed, or present as certain: Dün sinemaya gittim means “I went to the cinema yesterday.” Its basic shape is verb stem + -di/-dı/-du/-dü (or -ti/-tı/-tu/-tü) + personal ending. Harmony changes the suffix, but the meaning stays the same: geldim, yaptım, gördüm, okudum.

Overview

The -di past, traditionally called -di'li geçmiş zaman or görülen geçmiş zaman, is the everyday Turkish tense for definite, completed past events. A tense is simply a verb form that locates an event in time. You use this form to say what you did yesterday, report what happened in a meeting, ask what somebody said, or state a historical fact as established information.

This is a core A2 topic. Turkish does not need a separate word equivalent to English “did” in ordinary past statements or questions. Instead, the verb carries a past suffix and a personal ending: geldim is literally built from “come + past + I,” while Geldin mi? means “Did you come?” Turkish often leaves out the subject pronoun because the ending already identifies the subject.

The label “witnessed past” is useful, but it is not the whole story. -di can describe something you personally saw or did, but it can also present a fact you know with confidence: Atatürk 1881'de doğdu (“Atatürk was born in 1881”). The important contrast is with -miş, which often marks information learned from someone else, inferred from evidence, or newly discovered. Beginners can first master -di as the normal definite past, then refine that contrast later.

How It Works

Find the verb stem

Turkish dictionary forms end in -mek or -mak. This is the infinitive ending—the form corresponding to English “to” in “to come.” Remove it to find the stem (the base to which suffixes attach).

Infinitive	Stem	Meaning
gelmek	gel-	to come
yapmak	yap-	to do, make
görmek	gör-	to see
okumak	oku-	to read, study
içmek	iç-	to drink
beklemek	bekle-	to wait

The complete pattern is:

verb stem + negative suffix if needed + past suffix + personal ending

So gel-me-di-m breaks down as come-not-past-I: “I did not come.”

Choose the suffix vowel

The past suffix follows four-way vowel harmony: its vowel changes to match the final vowel in the stem. Vowel harmony means that vowels within a Turkish word tend to belong together in a predictable way.

Last vowel before the past suffix	Past-suffix vowel	Example
e, i	i	gel-di, bil-di
a, ı	ı	anla-dı, yap-tı
o, u	u	oku-du, bul-du
ö, ü	ü	gör-dü, düş-tü

Always look for the last vowel, not the first one. Thus konuşmak has final vowel u and gives konuştu; hazırlamak has final vowel a and gives hazırladı.

Choose d or t

After a voiceless consonant, the initial d of the suffix becomes t. The relevant voiceless consonants are ç, f, h, k, p, s, ş, t, often memorized in Turkish with the phrase fıstıkçı şahap.

Stem ending	Result	Why
gel-	geldi	l is voiced, so use d
yap-	yaptı	p is voiceless, so use t
iç-	içti	ç is voiceless, so use t
bak-	baktı	k is voiceless, so use t
düş-	düştü	ş is voiceless, so use t
oku-	okudu	a vowel precedes the suffix, so use d

These two harmony rules produce eight possible forms: -di, -dı, -du, -dü, -ti, -tı, -tu, -tü. They are variants of one suffix, not eight separate tenses.

Add the personal ending

A subject is the person or thing performing the action. Turkish shows the subject through the ending attached after the past marker.

Person	Form of gelmek	English
ben	geldim	I came
sen	geldin	you came (singular, informal)
o	geldi	he/she/it came
biz	geldik	we came
siz	geldiniz	you came (plural or polite)
onlar	geldiler / geldi	they came

The endings harmonize too. Compare yaptım, yaptın, yaptık, yaptınız with gördüm, gördün, gördük, gördünüz. In the first- and second-person plural, note the different patterns: -k for “we,” but -niz/-nız/-nuz/-nüz for “you.”

Subject pronouns are usually unnecessary: Kahvaltı yaptık already means “We had breakfast.” Add biz when contrasting or emphasizing: Biz yaptık, onlar yapmadı (“We did it; they didn’t”).

With a stated plural subject, the third-person plural ending is often omitted, especially with things and sometimes with people:

• Çocuklar geldi or Çocuklar geldiler — “The children came.”
• Otobüsler geçti — “The buses passed.”

Using a singular verb with a plural noun does not make the event singular. The noun already carries the plural meaning.

Full patterns across the harmony groups

Person	gelmek	yapmak	okumak	görmek
I	geldim	yaptım	okudum	gördüm
you (singular)	geldin	yaptın	okudun	gördün
he/she/it	geldi	yaptı	okudu	gördü
we	geldik	yaptık	okuduk	gördük
you (plural/polite)	geldiniz	yaptınız	okudunuz	gördünüz
they	geldiler	yaptılar	okudular	gördüler

Make a negative sentence

Put -me/-ma between the stem and the past suffix. Because this negative suffix ends in a vowel, the following past marker begins with d.

Positive	Negative	English negative
geldim	gelmedim	I did not come
yaptı	yapmadı	he/she did not do it
okuduk	okumadık	we did not read/study
gördünüz	görmediniz	you did not see
içtiler	içmediler	they did not drink

English-speaking learners may expect a separate “did not,” but Turkish keeps everything in one verb word: anlamadım means “I did not understand.”

Ask questions

For a yes/no question, first conjugate the past-tense verb, then add the question particle mı/mi/mu/mü as a separate word. A particle is a small grammar word used to build a particular structure.

Statement	Question	English
Geldin.	Geldin mi?	Did you come?
Yaptınız.	Yaptınız mı?	Did you do it?
Okudu.	Okudu mu?	Did he/she read it?
Görmediler.	Görmediler mi?	Didn’t they see?

The particle’s vowel follows the last vowel of the conjugated verb: geldi mi, yaptı mı, okudu mu, gördü mü. Unlike English, a question word such as ne (“what”), kim (“who”), or neden (“why”) does not normally take this particle:

• Ne dedin? — “What did you say?”
• Dün kimi gördün? — “Whom did you see yesterday?”
• Neden gelmediniz? — “Why didn’t you come?”

A few important-looking forms

Turkish past conjugation is highly regular, but spelling at the join can make some forms look surprising:

• gitmek → gitti and etmek → etti: the stem-final t meets -ti, producing the written double tt.
• demek → dedi (“said”) and yemek → yedi (“ate”) use the vowel stems de- and ye- in this tense.
• Vowel-final stems take the suffix directly: başladı, bekledi, okudu.

Learn dedi and yedi as high-frequency forms. Do not insert an English-style auxiliary before them.

Examples in Context

Turkish	English	Note
Dün sinemaya gittim.	I went to the cinema yesterday.	First-person definite past
Sabah erken kalktık ve kahvaltı yaptık.	We got up early and had breakfast.	Two completed actions
Ne dedin?	What did you say?	Question word; no mi
Toplantı saat üçte başladı.	The meeting started at three.	Vowel-final stem
Anahtarlarımı evde unuttum.	I left my keys at home.	unut- + -tu-m
Dün akşam seni aradım ama cevap vermedin.	I called you last night, but you didn’t answer.	Positive and negative
Bu kitabı daha önce okudunuz mu?	Have you read this book before?	Turkish -di can match English present perfect
Çocuklar parkta oynadı.	The children played in the park.	Plural subject with singular verb
Otobüsü kaçırdık, bu yüzden geç kaldık.	We missed the bus, so we were late.	Sequence of consequences
Ayşe yemeği hazırladı, Kerem masayı kurdu.	Ayşe prepared the meal, and Kerem set the table.	Two stated subjects
Geçen yıl Ankara'da yaşadım.	I lived in Ankara last year.	Finished time period
Kapıyı kim açtı?	Who opened the door?	kim is the subject
Bu sabah kahve içmedim.	I didn’t drink coffee this morning.	Negative form
Atatürk 1881'de doğdu.	Atatürk was born in 1881.	Established historical fact
Eve vardınız mı?	Did you get home?	Polite or plural “you”

English translations do not map one-to-one to Turkish tense labels. Depending on context, okudum can be “I read,” “I have read,” or occasionally “I did read.” Turkish chooses -di because the reading is presented as a definite past event; English chooses its tense according to its own time and discourse rules.

Common Mistakes

Using only one suffix shape

• Wrong: Dün film gördım.
• Right: Dün film gördüm.
• Why: The final vowel of gör- is ö, so the past vowel must be ü. Check the last stem vowel before choosing among ı, i, u, and ü.

Forgetting consonant harmony

• Wrong: Kahvaltı yapdık.
• Right: Kahvaltı yaptık.
• Why: After voiceless p, the past marker begins with t. The same rule gives baktı, içti, and düştü.

Adding an English-style “did” word

• Wrong: Ne yaptın mı?
• Right: Ne yaptın?
• Why: Yaptın already contains past tense and “you.” A question word such as ne makes this an information question, so mı is not added.

Attaching the question particle

• Wrong: Geldinmi?
• Right: Geldin mi?
• Why: The question particle is written separately, even though its vowel harmonizes with the verb.

Putting negation after the tense

• Wrong: Gelmeditim.
• Right: Gelmedim.
• Why: The order is stem + negative + past + person: gel-me-di-m. There is only one past suffix.

Overusing the plural verb ending

• Awkward: Arabalar geçtiler.
• Natural: Arabalar geçti.
• Why: With a plural subject, especially a nonhuman one, Turkish commonly leaves the verb in third-person singular. With people, both patterns occur, but the shorter form is often neutral.

Usage Notes

Definite does not always mean personally witnessed

A speaker can use -di for direct experience—Onu dün gördüm (“I saw him/her yesterday”)—but also for accepted knowledge, records, and facts. News reports and historical writing frequently use -di when presenting events as established. It would therefore be too strict to translate the suffix as “I personally saw this.”

English simple past and present perfect may both correspond to -di

English distinguishes “I saw that film” from “I have seen that film.” Turkish may use O filmi gördüm for either, with context and time expressions doing much of the work. Do not try to select a Turkish tense by translating the English tense name alone. Ask how the speaker presents the information.

Time words are useful, not compulsory

Words such as dün (“yesterday”), geçen hafta (“last week”), and iki saat önce (“two hours ago”) make the timing clear, but the suffix itself already marks the past. Bitirdim can stand alone as “I finished it / I’ve finished.”

Pronouns add contrast

Normally, aldım is enough for “I bought/took it.” Use ben when the identity matters: Ben aldım, Ali değil (“I took it, not Ali”). English requires an explicit subject in a normal sentence; Turkish generally does not.

Beyond the Basics / Advanced Use

You do not need to master all of these points at A2, but they explain forms you will meet later.

The contrast with -miş

Compare these two statements:

Form	Typical perspective	Possible English rendering
Ali geldi.	The speaker presents Ali’s arrival as definite	Ali came.
Ali gelmiş.	The speaker heard, inferred, or has just discovered it	Apparently Ali came. / I hear Ali came.

The distinction concerns evidentiality, meaning how the speaker presents the source of information. It is not a mechanical “seen versus unseen” test: established facts can take -di, while -miş can express surprise at something now visible. The full contrast belongs to later study.

Past forms with nouns and adjectives

The same past element appears in sentences whose predicate is a noun or adjective rather than an action verb. A predicate is what the sentence says about its subject.

• Yorgundum. — “I was tired.”
• Öğrenciydik. — “We were students.”
• Evde miydiniz? — “Were you at home?”
• Hazır değildi. — “He/she was not ready.”
• Param yoktu. — “I had no money.”

Here -ydi/-ydı/-ydu/-ydü follows a vowel, while -di/-dı/-du/-dü follows a consonant. Questions have forms such as miydi because the past marker attaches to the question particle. These “past of to be” patterns deserve separate practice; do not use verbal negation -me/-ma with adjectives or nouns.

Compound tenses

At higher levels, -di follows another tense or aspect form to create compound tenses:

• geliyordum — “I was coming”
• gelecekti — “he/she was going to come”
• gelmişti — “he/she had come”
• gelirdi — “he/she used to come / would come”

In these forms, -di places a larger verb form in a past viewpoint. Learn them as later extensions rather than treating every d/t near the end of a verb as the simple -di past.

Storytelling and sequencing

A chain of -di forms moves a story forward through completed events: Eve geldim, üstümü değiştirdim, yemek yedim ve uyudum (“I came home, changed my clothes, ate, and slept”). Background actions and habits often require compound forms such as -iyordu or -irdi. This difference becomes important when you move from listing events to telling richer stories.

Practice Tips

1. Build an eight-form harmony grid. Choose one verb for each pattern—gelmek, bilmek, yapmak, anlamak, bulmak, okumak, görmek, düşmek—and say the third-person forms aloud: geldi, bildi, yaptı, anladı, buldu, okudu, gördü, düştü.
2. Keep a three-line daily diary. Write what you did, what you did not do, and one question for a friend: Bugün çalıştım. Spor yapmadım. Sen ne yaptın? This rehearses positive, negative, and question forms together.
3. Parse long forms from right to left. In görmediniz, identify -niz (“you”), -di (past), -me (not), and gör- (“see”). This makes Turkish suffix chains feel systematic rather than long and unfamiliar.
